It is interesting to noted that the frequency never drops when Turbo Core is disabled and the processor operates at 3.80GHz all the time. As it turns out, in certain cases AMD’s chips deliver lower performance than they are supposed to.

AMD appears to know about the decrease of clock-speed below the base level and claims that it occurs in very rare cases under loads that are not typical for client microprocessors.

Our SETI apps very that "non-typical" case that plagues both of my Trinity APUs.
AMD didn't do things right again :/

By design, the clocks may be throttled even below the base frequency when worst-case high-power applications (non-typical to market segment e.g. HPC app in this case) are run. In other words, base frequency is designed such that it is sustainable (i.e. APU operating at or above base) for most, if not all, typical applications relevant for the market segment. […] It would be a problem and unfair if these “tests” ended up ruining the life span of our customers’ products,” concluded Mr. Amos.

So, AMD dictates now HOW to use bought CPUs! No matter that you paid for particular performance and particular freqs. If you use CPU not in "proper" way it will underperform and that's "just right" ??? I would say they should use better thermal design then! Just hidden costs for users. Disgusting move :/
